From e0fa7ab42232e742dcb3de9f3c1f6127b5adc019 Mon Sep 17 00:00:00 2001 From: Riccardo Mancini Date: Thu, 15 Jul 2021 18:07:25 +0200 Subject: perf probe-file: Delete namelist in del_events() on the error path ASan reports some memory leaks when running: # perf test "42: BPF filter" This second leak is caused by a strlist not being dellocated on error inside probe_file__del_events. This patch adds a goto label before the deallocation and makes the error path jump to it.
